Dendritic cells as key players in systemic lupus erythematosus

Abstract

System lupus erythematosus (SLE) is a chronic autoimmune disorder affecting multiple organs, and persistent disease activity is associated with increased morbidity and mortality. Impairment of immune cell function and loss of immune tolerance to self-antigens are significant determinants that trigger inflammation and drive SLE pathogenesis. Dendritic cells (DCs) are the most potent antigen-presenting cells that serve as a critical link between innate and adaptive immune system. SLE development and pathogenesis are associated with aberrant regulation in homeostasis and function of DCs, therefore, DC-targeted therapies have become of importance for treatment of SLE and autoimmune diseases. This review focus on the significance of DCs in promoting of SLE pathogenesis, and further discuss the clinical potential of DCs in SLE therapy. The insights on the roles of DCs in SLE will provide the improvement of treatment strategy for SLE patients.
